NOTE
z If the calibration fails, check for technical alarm and troubleshoot it if there is.
Then do the calibration again.
z In case of repeated calibration failures, replace the O
2
sensor and do the 21% O2
calibration again. Calibrate at 100% O2 again after 21% O2 calibration is
completed. If it still fails, contact your service personnel or us.
To calibrate at 100% O
2
